+Cosmology Calculator
+====================
+
+The cosmology calculator can be used to calculate cosmological distances and
+times given a set of cosmological parameters. A cosmological dataset, `ds`,
+will automatically have a cosmology calculator configured with the correct
+parameters associated with it as `ds.cosmology`. A standalone
+:class:`~yt.utilities.cosmology.Cosmology` calculator object can be created
+in the following way:
+
+.. code-block:: python
+
+ from yt.utilities.cosmology import Cosmology
+
+ co = Cosmology(hubble_constant=0.7, omega_matter=0.3,
+ omega_lambda=0.7, omega_curvature=0.0)
+
+Once created, various distance calculations as well as conversions between
+redshift and time are available:
+
+.. notebook-cell::
+
+ from yt.utilities.cosmology import Cosmology
+
+ co = Cosmology(hubble_constant=0.7, omega_matter=0.3,
+ omega_lambda=0.7, omega_curvature=0.0)
+
+ # Hubble distance (c / h)
+ print co.hubble_distance()
+
+ # distance from z = 0 to 0.5
+ print co.comoving_radial_distance(0, 0.5).in_units("Mpc/h")
+
+ # transverse distance
+ print co.comoving_transverse_distance(0, 0.5).in_units("Mpc/h")
+
+ # comoving volume
+ print co.comoving_volume(0, 0.5).in_units("Gpc**3")
+
+ # angulare diameter distance
+ print co.angular_diamter_distance(0, 0.5).in_units("Mpc/h")
+
+ # angular scale
+ print co.angular_scale(0, 0.5).in_units("Mpc/degree")
+
+ # luminosity distance
+ print co.luminosity_distance(0, 0.5).in_units("Mpc/h")
+
+ # time between two redshifts
+ print co.lookback_time(0, 0.5).in_units("Gyr")
+
+ # age of the Universe at a given redshift
+ print co.hubble_time(0).in_units("Gyr")
+
+ # critical density
+ print co.critical_density(0)
+
+ # Hubble parameter at a given redshift
+ print co.hubble_parameter(0).in_units("km/s/Mpc")
+
+ # convert time after Big Bang to redshift
+ my_t = co.quan(8, "Gyr")
+ print co.z_from_t(my_t)
+
+ # convert redshift to time after Big Bang (same as Hubble time)
+ print co.t_from_z(0.5).in_units("Gyr")
+
+Note, that all distances returned are comoving distances. All of the above
+functions accept scalar values and arrays. The helper functions, `co.quan`
+and `co.arr` exist to create unitful `YTQuantities` and `YTArray` with the
+unit registry of the cosmology calculator. For more information on the usage
+and meaning of each calculation, consult the reference documentation at
+:ref:`cosmology-calculator-ref`.
